To .all whom t'mag/ concern.' v l"Be it known that I, BERNARDJ.2GARN\nR-, aicitizen of the EUnited States, residing iat CrossfPlains, in the county. of LCallahan.:and State of Texas, `have inventedcertaindnew and uiseful Improvements in a Glamp,'of whichf the followinglis la specification.

:The present invention relates to `an -im-l provement in clamps and isintended vfor use inholdingthe line `or cable to fwhich is attached thetools linfdrilling deep wells of every1 description. The: clamp Sis-`adapted to be suspended below the itemper `screw by linksya-nd isadapted-tolhold the line or cable so firmly thatthe Aweight-ofthe toolscannot slip the ilinefthrough it so that the Atool can only'des'cend asset out 'by the temperscrew.

An important objectofi the invention is "to provide-a clampx of thisnature which isy eX- ceedingly simple Kin its yconstructiom satisfactory`in itsoperation", efiicient, reliable, strong, fdurable, -easy -tomanipu'late, not likely to become easily outof orden-compact, `and`otherwise well yadapted tokthe purpose for'which'itis designed.

ithfthe'above and `numerous other fobjectsiin view as will appear Lasthe description proceeds, the inventionresides in'cer'- tain novelfeatures of construction, land in thecombination and arrangement ofpartsas -will fbe .hereinafter y'more fully described and claimed.

In the drawing -Figure j1 .is atop plan View of they clamp embodyingthe'features ofimy invention.

Figure 2 is a side elevation thereof showing one of the slips insection.

Figure 3 is a horizontal section through the clamp, and K Figure 4 isanotherl side elevation of the device.

Referring to the drawing in detail it will be seen that the numerals 5designate a pair of jaws. The outer side edges of these jaws 5 areprovided with notches 6. Transversely disposed slip receiving portions 7are provided on adjacent ends of the jaws 5 andthe notches 6 aredisposed closer to these ends of the jaws than to the other ends. Thetransversely extending slip receiving portions 7 are provided withoutwardly extending curved hooks 8 at adjacent ends. The inner edges ofthe portions 7 are grooved longitudinally as at 9, eX- tending from theend provided with the hooks and terminating a slight distance from .theotherends-as is lclearly vshown in Figure a2. These groovesitaper fromtheir bottom endsfupwardlysand receive similarly tapered slips 10 having=tlieir .upper vends 60, provided with transversely .extendingaperturedv kears ll l.which are j positioned y over :the upper fends `ofthe portions -7 and held 1in place by screws 12,itheiline1or1cable 13'is adapted lto be received `yin the grooves lof thel slipslOiintheusualfmanner. 2 .Thehooks Stof coufrse,.are adapted to'lbe:engaged :inthe links :suspended from 5.the temper isere-w,

.-'A' :yoke or substantially 'rectangu'larly shaped frame "134 isprovided onits=end}por 70 tions with inwardly disposed 'fulcrums T15adapted to be received inthefnotclies'aslis clearly shown in F igure3..A pin .16='eX tends cent-rally and .transversely :across y'the yoke orframe 14 and has disposed thereon 75 a sleeve :or .roller :17 iforengaging ztheiinner sides `:of 'the jaws .5 thereby fholding thenotchesw in engagement awith ithe fulcrums and preventing ftlrevdisassembling of Ethe jaws .from '.the L-zyoke iuntil this ipin 16isvso removed. v:The apin 16 is :preferably r held fin placeby Cotterfpins 18 :extending ,through the ends fthereofto 5the .outside of thelongitudinal portions .of v.the rectangular @frame 154.1as will be'evident froman .-inspectionof 85 Figures -1 and 4." .The fends 19fofthe ijaws .5 are provided' with notches*20,;tl1e`entrances to whichare= disposedl toward each other as may be '.seenin v'Figure l.Ascrewfblock 21 vis `xprovided "with voppositel'y Ldisposed 9otrunnionsz22.- receivable iin the notches: 201 on one end 19 while aseat block 23 has its oppositelyr disposed trunnions 24 receivable inthe other notch 20. The trunnions 22 and 24 are held againstdisplacement from the 95 notches 20 by cotter pins 25. The screw block21 is provided with a longitudinally extending screw threaded bore forreceiving a T-screw 26. The seat block 23 is provided with a seat 27 forreceiving the end of the 100 T-screw 26 which is preferably pointed forseating in the recess 28. A spring 29 is attached to the outer end ofthe screw block 2ly and as at 30 and to an intermediate portion of theadjacent jaw 5 as at 31 and tends 105 to swing the inner end of theblock 21 outwardly so that the end of the screw 26 will be properlyseated in the lock 23.

By turning the screw 26 so that it will clamp the lineor cable 13between the slips 10. If for any reason it should be desirable, thescrew 26 can be slightly loosened so as to let the clamp slip. This isdesir-.

- merely by way of example and attains all the features of advantageenumerated as desirable inthe sta'tement of the invention and the abovedescription. It will be apparent that numerous changes in the details ofconstruction, in the sizes, and the materials, in the combination andarrangement of parts as may be resorted to without departing from thespirit or scope of the invention as hereinafter claimed or sacrificingany of its advantages.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is l.v In a clamp of 'the class described, arectangularly shaped yoke having its ends provided with inwardlyextending fulcrunis, a pair of jaws having their outer edges providedwith notches vfor receiving the fulcrums, a pin extending transverselyof the yoke and engaging the inner edges of the jaws for holding thenotches 'thereof in engagement withthe fulcrums, a screw block pivotedin one end of onejaw, a seat block pivoted in the same end of the otherjaw, a screw threaded through the screw block and engageable in the seatblock, and slips provided 1n the other ends of the jaws.

2. In a clamp of the class described, a rectangularly shaped yoke havingits ends provided with inwardly extending fulcrums, a pair of jawshaving their outer edges provided with notches for receivingthefulcrums, a pin extending transversely of the' yoke and engaging theinner edges of the jaws for holding the notches thereof in engagementwith 'the fulcrums, a screw block pivoted in one end of one jaw, a seatblock pivoted in the same end of the other jaw, a screw threaded throughthe screw block and engageable in the seat block, the other ends of saidjaws being provided with transversely extending slip receiving portionshaving their upper ends provided with outwardly and downwardly curvedhooks and their inner edges provided with tapered grooves, tapered slipsreceivable in said grooves.

` 3. In a clamp of the class described, a rectangularly shaped yokehaving its ends provided with inwardly extending fulcrums, a pair ofjaws having their outer edges provided with notches for receiving thefulcrums, a pin extending transversely of the yoke and engaging theinner edges of the jaws for holding the notches thereof in engagementwith the fulcrums, a screw block pivoted in one end of one jaw, a seatblock pivoted in the same endof the other jaw, a screw threaded throughthe screw block and engageable in the seat block, the other ends of saidjaws being provided with transversely extending slip receiving portionshaving their upper ends'provided with out wardly and downwardly curvedhooks and their inner edges provided with tapered grooves, tapered slipsreceivable in said grooves, said slips provided with lateral extensionsat their upper ends provided with openings, and screws extending throughsaid openings into the upper ends of the portions.
